Settings Conversion Calculator

The Settings Conversion Calculator will convert existing trip unit settings to AC-PRO-II or AC-PRO trip unit settings.

Disclaimer: The Settings Conversion Calculator is intended to be used as a starting point to match existing settings. Converted settings may not exactly match existing. Final settings should be determined by a Protection Engineer or other Qualified Person. Settings affect Safety, Equipment (assets), Processes, etc. The process of determining settings requires additional information such as application-specific studies. These studies can include Short Circuit, Protection/Coordination, Arc Flash, etc. Simply converting existing settings may not be adequate or appropriate. URC is not responsible for determining adequacy, appropriateness or results of improper settings.

By logging in, you are acknowledging that settings are to be used as a starting point and final settings should be determined by a protection engineer or other qualified person. If your existing trip unit is not included in the tool, contact URC and we’ll put it in the queue.
